ClimaCLEAR allows for maximum transparency with no vertical stiles providing natural daylighting, open views, and a clean, modern appearance making it suitable for all design styles.

  • In moderate climates: Use to create an indoor/outdoor lifestyle in living rooms, dining rooms, and kitchens.
  • In colder climates: Extend the seasonal enjoyment of outdoor patios, three season rooms, or porches. Create a transparent shelter from the elements without inhibiting the connection to the outdoors.
  • In commercial settings or sport venue applications: Provide maximum viewing and unobstructed sightlines even when closed.

Transparent Vertical Weather Seals

Standard between all sliding panels and single action swing panels are super clear vertical seals to seal against wind driven rain and to reduce air infiltration. The seals virtually disappear from sight. Light transmittance (LT) of the weather seals has been independently tested and rated for 75% clarity and luminosity.


All horizontal continuous door rails come standard equipped with double fin brush seals on both sides, top and bottom, for weather protection.

Patented Panel Interlocks to help keep the weather out

Proprietary male/female panel interlocks at the top and bottom rails are designed to help keep the weather out. Panel floor bolts are foot activated effectively locking the panel into place without the need to kneel down.

System Security

Structural integrity of the system is achieved through the combination of strong rollers, the clamping of the 1/2” (12 mm) monolithic glass, and through panel locking. Each closed panel of ClimaCLEAR can be securely locked in place. Standard to the swing panel is the Reverse Tubo200 handle/locking system with the handle starting at hand height and extending up to the top rail, outfitted with inside/outside locking and an additional lock at the bottom rail. The system has passed forced entry requirements.


Intelligent Rollers Provide One Hand Operation

German engineered roller system ensures quiet, smooth, and trouble free single hand operation by using an “intelligent” guiding system for moving individual panels one at a time.
